Welcome to the Support Communities!
Many times, just resetting the iPhone and/or turning it off and then back on resolves most issues.
If you feel that you need to do more troubleshooting with iCloud, this article may help:

Resetting my phone does the trick, but doesn't solve the issue. Just today a large majority of my contacts disappeared again. I just waited it out and they eventually came back within 15 or so minutes. It's really annoying and I don't think that just resetting the phone is the answer. iCloud isn't the issue either. I didn't have this trouble until iOS7 came out.

I have found a solution faster that shuting off your iphone. Go to settings>Mail,contacts,calendar>iCloud. Turn contacts OFF but when it asks you to keep contacts or delete select "keep contacts on iphone". After you do that turn contacts back on and boom! They come back in your contacts app as well as your messages.

Alpha_By_7 what can I say? Great idea!!! Now all my iCloud contacts are gone.
So listen people this keeps happening, it happened once to me and now it happened again and they are not coming back. All my iCloud contacts are GONE!
My soolution is get away from iCloud and run the other direction as fast as you can. Obviously this is a BAD PIZZA and the big lesson learned is that whatever Apple is doing it is NOT always right. Nobody has given the company immunity from mistakes.

This has happened to me as well, several times!
As a direct result of the contacts being "dropped" monetarily, you lose all custom settings for the people you have added ring tones and text tones to.
At this point this isn't a simple issue, its a full on inconvenience id say.

Thank goodness this isn't just me!! I have alot of contacts and use them for work purposes. I add new contacts to my phone no probs. Then sometimes just randomly all my contacts disappear, sometimes they come back a few minutes later but today it was over an hour and once back there is no guarantee all my contacts are back. The newest ones are definitely not there......today that was 43 contacts I have to reprogram into the phone!! This is very worrying as I provide much needed support to people and if they disappear I won't know without constantly checking. I was syncing with icloud and an ipad2 but I'm really not sure what to do.......any tips?

When is Apple going to fix this? This is still a recurring problem. I have iCloud completly turned off, except for Find my iPhone. I regularly backup my iphone via iTunes (locally). I have the latest version of iOS. I have only 1 set of Contacts. But at least once a week, a significant portion of my contacts just vanish. Usually I notice this when contact names revert to phone numbers in Messaging or Contact Favorites. This has been happening for about the past 2 months. This never happened with iOS 6.x.
The ONLY workaround I have found is to reboot/wait an hour, or do a RESTORE via iTunes.
This is NOT a user error. This is not me using the phone incorrectly or messing with the settings.
This is a bug in iOS7, and its about time Apple fess up and fix it in a service pak.

As of March 3, 2014, this is still an issue.
iOS version: 7.04 (/7.05)
Occured either sometime, or immediately after backing up phone to the cloud. All contacts but 1 disappeared. It has been like this for at least 24 hours. I'm overdue for the SSL patch, going to see if it persists after version update...
A subsequent power cycle elicits no change.
Strangely, there is a circular arrow (presuming 'refresh') in the top left corner of my contacts menu. When I click it, it chugs away for a second, then pops up a 'Password Incorrect' error message with the subtext:
Enter the password for the Outlook account "Remove Account"
Wait, what? What Outlook account is it talking about, and what does it have to do with my contacts? I most certainly don't have an account named "Remove Account".
I tried pressing enter with a null password field, the phone thought for a second, and the popup goes away without any complaints. Still no change in contacts.
Seems clear not an isolated incident, and from thread history, has persisted throughout the entirety iOS 7.x.
Will continue searching for a workaround that works for me. Until then, I'll just have to remember my entire contact list. Everything except for Mobile Music.

Same problem here. Woke up this morning and 80% of my contacts are gone. Going on a trip today and don't have time to figure this out + I need my contacts. ***? Also have problem with calendars not synching. Deleted iCloud but no dice. I'm not techie and have apple products because they're all supposed to work. Why can't I just slide my macbook data (contacts and calendars) onto the phone to update it when it's connected? Should I go back to a PC world?

OK figured my problems out. In itunes go to Info menu and check appropriate sync for calendars and contacts. The next sync restored my Contacts and Favorites. Somehow those boxes became unchecked during iCloud dismantle or 7.06 upgrade or some such other transaction.
